    摘要: High molecular weight polyester fibers having excellent mechanical strength and useful for various industrial materials, is produced by dry-jet wet spinning a dope solution of a polyester resin comprising repeating ethylene terephthalate units, having an intrinsic viscosity of 1.2 or more and dissolved in a phenolic solvent, through a spinneret, coagulating the resultant filamentary dope solution streams in a bath of coagulating liquid in which the phenolic solvent is soluble and the polyester resin is insoluble, while controlling the temperature of the coagulating liquid to a level of from (Tg-50.degree. C.) to (Tg+45.degree. C.) wherein Tg represents a glass transition temperature of the dope solution, and optionally subjecting the resultant undrawn polyester filaments to a rinsing step with a rinsing liquid, to a drawing step at a total draw ratio of at least 5, and to a heat-treating step.
